Yeah, I added 7 of the big cans. I think it was close to 7 pounds. The latest one that I did has about 6 pounds of roasted pumpkin meat that I cooked myself from fresh picked pumpkins. Turns out really nice, but the pumpkin adds heaps of starch for coversion in the mash. The beer will be really alcoholic from the simple sugars created from the pumpkin starches.
